SolarStriker is a vertically scrolling shooter developed by Nintendo R&D1 with Minakuchi Engineering for the Nintendo Game Boy. It was first published in Japan on January 26, 1990, then released later in North America on February 2, 1990, and finally in Europe on September 28, 1990.
The player controls the advanced space fighter, code-named Solar Striker. There are six levels of play against enemies known as the forces of Reticulon. These enemies appear from the top of the screen. The player can amass power-ups by shooting special ships. One power-up doubles the player's firepower, three power-ups triples the player's firepower, and five power-ups causes shots to explode on impact with enemies, greatly aiding combat against tough enemies and bosses that take many hits to destroy. There are a variety of enemies as well as sub-bosses in later levels. When the player completes all six levels for the first time and after the credits roll, the player will be able to play Hard Mode by pressing Select instead of Start from the title screen.
